Just because you can doesn't mean you should..

Dead is dead regardless of the means. When the brain stops working it can't ask if it was stopped by a .223 or a bomb going off, it is just dead.

The “why” is obvious - shock value/blood and guts.

Same reason guys blow them up with tannerite while they’re laughing and high-fiving.

I don't like hogs, but I think they deserve a clean quick kill if possible. I'm guilty of not pulling that off, and I don't feel good when they suffer. Ran into this a month back when we were night hunting and ran out of ammo and had one refusing to die like all of us do. It was messy and I will remember from that night forward to always have plenty of ammo and my sidearm, which I usually have but didn't on this night. Didn't have my pig sticker either so trying to finish off with a knife not suited for the task was not a memory I'll cherish.

Well which is it?

He should just shoot the wad at the pig. Maybe we could end the debate about knock down power.

If ya don't plan on eating it and kill pigs with it,,,,why not use it ? We don't eat all the pigs we kill.
